【摘要】:目的 分析足月妊娠羊水偏少孕妇阴道试产对妊娠结局的影响,,探讨胎儿生物物理评分(BPS)、缩宫素激惹试验(oxytocin challenge test, OCT)及宫缩应激试验(contractionstress test, CST)在羊水偏少孕妇阴道试产中的临床意义。 方法 收集2012年1月-2013年1月在泰山医学院附属医院定期产前检查并住院分娩的足月妊娠羊水偏少的孕妇85例作研究组,入组孕妇均符合以下标准:妊娠足月、单胎、头位,排除胎儿畸形,入院前1-7d内行产科彩超,5cm羊水指数(AFI)≤8cm,且入组病例有完整的临床资料。随机选择同期羊水正常的足月妊娠孕妇80例作为对照组。两组孕妇入院后均给予电子胎心监护无应激试验(non-stress test, NST)、Bishop子宫颈成熟度评分、缩宫素激惹试验(oxytocin challenge test, OCT),及临产与否。根据孕妇入院的实际情况,予选择性剖宫产、阴道试产及选择性引产处理。在阴道试产过程中,严密持续的监护,分别对两组病例进行回顾性分析。 结果 本研究发现研究组与对照组剖宫产率比较,P0.05,差异有统计学意义。产前研究组和对照组出现变异减速(VD)分别为6例,4例,P0.05,差异无统计学意义;产前两组均无晚期减速(LD)出现;产时出现VD分别为17例,4例,P0.05,差异有统计学意义;产时两组出现晚期减速(LD)分别为3例,2例,P0.05,差异无统计学意义。两组羊水I度胎粪污染分别为24例,12例,P0.05,差异有统计学意义,两组II度、III度胎粪污染P0.05,差异无统计学意义。两组发生胎儿窘迫分别为9例,6例,P0.05,差异无统计学意义。研究组和对照组新生儿Apgar评分小于7分的分别为18例,7例,P0.05,差异有统计学意义,研究组和对照组新生儿Apgar评分小于4分的分别为3例,2例,P0.05,差异无统计学意义。羊水偏少组与羊水正常组新生儿的体重P0.05,差异无统计学意义。 结论 在严密的产前及持续的产时监护下,足月妊娠羊水偏少孕妇可以进行阴道试产,并且能够有效的降低剖宫产率。对于在宫腔内状况良好的胎儿,若患者子宫颈的条件成熟,并且没有出现其它高危因素,可以进行阴道试产,在试产过程中,应严密持续的监测BFHR的变化、产程进展的情况和羊水的性状,在恰当的时机终止妊娠,亦可获得良好的妊娠结局;若子宫颈条件不成熟,羊水偏少的孕妇可以选择性的促进宫颈成熟引产,尤其是可以选择性的使用地诺前列酮栓剂阴道后穹窿上药,可使得剖宫产率明显降低。

The clinical significance of CST in vaginal trial labor of oligohydramnios pregnant women. Methods from January 2012 to January 2013, 85 pregnant women with oligohydramnios in term pregnancy who were regularly prenatal checked and delivered in hospital in affiliated Hospital of Taishan Medical College were collected as study group. All the pregnant women in the study group met the following criteria: full term pregnancy, single pregnancy, and single pregnancy. In head position, fetal malformation was excluded, color Doppler ultrasonography was performed within 1-7 days before admission, 5cm amniotic fluid index (AFI) 鈮
